Description

Fixed casement for partition with thermal break

[0001] The invention refers to fixed casements for windows, doors or other partitions, in particular fixed casements with thermal break. The invention further refers to a method of placing and assembling fixed casements in separators, such as walls.

[0002] Common fixed casements for sliding leaves of windows, doors or other partitions have a lower profile with a guide or guides for one or more leaves, and an upper profile with a corresponding number of guides. If the sliding leaf slides within a panel or separator that separates two areas, e.g. a wall separating the interior and exterior of a building, the guides are partly inside a chamber that is configured within the panel.

[0003] If the leaf slides out of the panel, the guides are placed partly in contact with or close to one surface, usually the external surface of the panel.

[0004] To address thermal losses, the lower profile may be composite and consist of an aluminium profile, an aluminium side wall and a bottom between them. The aluminium profile is placed towards the external side of the building and the side wall towards the internal side. The bottom is made of insulating material and creates a thermal break between the aluminium profile and the side wall. The aluminium profile has at least one guide for the sliding leaf, but may also have several guides, e.g. for insect screens, shutters or a second sliding leaf with glass pane.

[0005] Despite the thermal break achieved with the composite profile, thermal losses are significant, due to the losses through the side wall of the composite profile, which is located towards the internal side of the building, whether it is inside the chamber of the panel or on an external surface thereof. It has been observed that on cold days, temperatures of the side wall are low, although this wall is located towards the interior of the building.

[0006] The object of the invention is a profile on which leaves of windows, doors or other partitions slide with a reliable and effective thermal break. The object of the invention is also a fixed casement for windows, doors or other partitions with reliable and effective thermal break. Another object of the invention is an effective insulation for a fixed casement or a frame. Another object of the invention is a method of assembling and placing such a fixed casement or a frame.

[0007] The invention is defined by independent claims.

[0008] The profile on which a leaf of window, door or other partition slides has a body with at least one guide, one side wall opposite the guide and one bottom between the body and the side wall, with the body, side wall and bottom forming a channel. The side wall extends from two opposite sides of a window. In the channel there is an insert made of insulating material, which exits from the channel through the window.

[0009] Such a profile minimises losses through this and in general through the fixed casement to which it belongs. The profile may be located inside a chamber, inside the panel or in contact with an external surface of the panel. The insulation of the frame is continuous, i.e. it creates a closed, non-flat cell. The invention is particular advantageous, when applied in aluminium profiles.

[0010] Dependent claims define characteristics that offer further advantages to the invention.

[0011] The side wall may be discontinuous and has two distinct independent components, which extend from the two opposite sides of the window.

[0012] Optionally, the bottom may be also discontinuous in the area of the insert.

[0013] In some embodiments the bottom is made of a material of different thermal conductivity from that of the body and side wall and is connected to the body and side wall. [0014] The bottom may consist of one or two components, each of which has two edges. Each edge is placed in a guide provided either in the body or the side wall.

[0015] The body may have one or more guides, which extend in parallel along a longitudinal direction. The guides are provided for sliding glass panes, insect screens, shutters or any other partition.

[0016] To achieve continuous insulation, the insert shall be in contact with an elongated insulating element located outside the channel. To facilitate assembly, the insulating element and the insert may have co-operating connecting components.

[0017] A profile according with the invention may be a component of a fixed casement of doors, windows or other partitions, in particular the upper rail and/or the lower rail of a fixed casement. When referring to a leaf that slides on a profile, it is meant that the leaf may also roll on the profile and the profile may be either below or above the leaf. In the former case the profile is a lower rail, which supports the profile, and in the latter an upper rail, from which the profile may be hung.

[0018] The insulating element may be placed between the separator, where the casement is fitted and an additional profile.

[0019] A continuous insulation in a fixed casement-frame of a window, door or other partition leaf according to the invention has a planar insulation, for example an insulation with two co-planar elongated branches, and one elongated branch outside this plane. In some examples, the co-planar elongated branches are three.

[0020] The method for placing a casement of a window, door or other partition leaf has following steps: (a) supporting a profile on a surface and partly inside the chamber of a panel or tangent to an external surface of a panel, e.g. a wall, with the side wall window of the profile being at least partially uncovered by the panel and the insert extending transversely from the panel and to the outside of the profile; and (b) supporting an insulating element along an edge of the panel and in contact with the insert.

[0021] An additional profile may be placed on the edge of the panel, with the insulating element located between the panel and the additional profile.

[0022] An important advantage of the invention is that it retains the element of the profile that is in the inner side of the building in the inside temperature or close to the inside temperature rather than the outside temperature.

[0023] Examples of the invention are described below in accordance with the following figures:

[0024] Figure 1 shows a sliding door placed on a wall (80) of a building, from the internal side of the building. Figure 2 shows the DD section of the door. In the example of Figure 2, the door has three sliding leaves: a leaf (71) bearing a single, double or multiple glass pane, a second sliding leaf - insect screen (72) and a sliding shutter (73). Other examples may feature one, two or more leaves.

[0025] Figures 3, 4, 5 and 6 present the lower profile (10) of the fixed casement or frame. The profile (10) has one body (12) with three guides (21, 22, 23), one side wall (14) and one bottom (16) between the body (12) and the side wall (14). Each one of the three leaves (71, 72, 73) of the door rolls on a respective guide (21, 22, 23). The leaf (71) bearing the glass pane is the one closest to the interior. Sliding of the leaf (71) may be facilitated by rolls on the guide (21).

[0026] In the example of Figure 6, the body (12) is a profile with a square cross-section tube and three guides (21, 22, 23). Channels are configured between two adjacent guides. A channel (18) is also configured between the body (12), the side wall (14) and the bottom (16). The channel (18) has an opening (19) opposite to the bottom (16).

[0027] The side wall (14) and the body (12) are two distinct aluminium components, joined by the bottom (16). The bottom (16) is made of a material of lower thermal conductivity than that of the body (12) and side wall (14), e.g. polyamide. In the example of Figure 6, the bottom (16) consists of two distinct, almost flat components. Each of the two components of the bottom (16) has two ends. Each one of the two ends is located in a channel configured on the side wall (14) and in a channel configured on the body (12) respectively. An alternative design of the bottom (16), which can be used in various examples of the invention, is a single component with internal spaces, as shown for example in Figure 7. Other configurations of the bottom (16) are anticipated by the invention.

[0028] The bottom (16) and side wall (14) are discontinuous. A window (15) is formed on the side wall, see also Figure 8, and the side wall (14) extends to the right and left of the window (15) with distinct components (141, 142). One of the two components (141) extends to the opening of the panel and the other component (142) is placed at least partially in a chamber (70) of the panel (80), in which the leaf (71) slides to the opening position. In the example of Figure 8, the bottom (16) is also discontinuous with distinct components to the right and left of the window (15) as the components (141, 142) of the side wall (14). In other examples, not shown in the figures, the window (15) of the side wall (14) may extend to its full height and the bottom (16) may not be discontinuous or may be partially discontinuous.

[0029] The guide (21) interlocks with an edge of the leaf (71) along the edge. A thermal insulating insert (24) is placed inside the channel (18), which is configured between the body (12), the side wall (14) and the bottom (16). The insert (24), which for example it may be from polymer polyamide, has one leg inside the channel (18), which projects from the window (15), transversely with respect to the side wall (14) outside the channel (18), as shown schematically in Figure 9. As schematically shown in Figure 10, the insert (24) bridges the bottom (16), which is the insulation between the body (12) of the lower profile (10) and the side plate (14) on the one hand and an insulating element (28), located outside the channel (18) on the other hand. The insulation-bottom (16) extends along the lower profile (10), in a longitudinal direction, usually horizontal in case the profile (10) is placed in a building. The insulating element (28) is also elongated and is arranged vertically. The insulating element (28) and the insulation-bottom (16) lie along two no co-planar lines - skew lines. With this arrangement the insulation-bottom (16), the insert (24) and the insulating element (28) form a continuous insulation that lies in two parallel planes, as shown in Figures 13 and 14.

[0030] When the fixed casement is fitted along the perimeter of an opening of a panel (80), e.g. on a building wall and the lower guide (10) is placed horizontally to the floor, the window (15) of the side wall (14) is placed in the perimeter area of the opening, so that it is not obstructed, at least partially, by the panel (80). The insulating element (28) extends vertically along the edge of the panel (80). At the edge of the panel (80) a profile (40) is vertically fixed. Such a profile (40) may be an aluminium profile that is also referred to as pseudocasement (40). The insulating element (28) is interposed, optionally compressed, between the panel (80) and the profile (40) - see Figure 4, showing the insulating element interposed between a hollow beam (29) and the pseudocasement (40). The hollow beam (29) is placed in a recess at the edge of the panel (80).

[0031] The invention facilitates the creation of continuous insulation at the perimeter of the opening of a panel with a pair of opposed, mostly parallel and horizontal, insulations inside the top and bottom profiles respectively, and an additional pair of two opposite, mostly parallel and vertical, insulations. At least one of the two vertical insulations, the insulation at the edge of the panel in the area where the chamber is located, is connected to the two horizontal insulations, by means of an insert. In the case of a partition with a sliding leaf on a guide, the two horizontal insulations and one vertical - the vertical which is on the edge of the panel where the lock is located - are co-planar and the insulation that is on the edge of the panel in the area of the chamber lies on another plane, as shown in Figure 13. In a two-leaf biparting sliding frame, i.e. with two sliding leaves on the same guide, the two horizontal insulations are inside the upper and lower guide and the two vertical ones lie in a plane parallel to the plane on which the horizontal ones lie. This layout is shown in Figure 14.

[0032] The profile and method of application can be applied to sliding leaves that slide into a chamber of a panel or slide externally, on an outer face, usually the external face of the panel (80). This latter type of application is shown in Figures 15 and 16. Figure 15 shows a layout with three sliding leaves and Figure 16 a layout with one sliding leaf, with the lower guide placed on the external surface of the wall (80), which has a notch at its edge. In some examples, a hollow beam (29) is provided in the notch.

[0033] Figure 15 shows an external sliding leaf on the guide (71) of the lower profile (10) of the fixed casement. In the case of Figure 15 and of Figure 16, the lower guide (10) is external and in contact with the wall - panel (80) - instead of entering a chamber. The insert (24) is located in the channel (18). At the edge of the panel (80) a profile (40), e.g. an aluminium profile, is vertically fixed with the insulating element (28) inserted and compressed, between the panel (80) and the insulating element (28). In external sliding biparting sliding frames, the two horizontal insulations are inside the upper and lower guide and the two vertical ones lie in a plane parallel to the plane where the horizontal ones lie, as shown in Figure 14. In external single-leaf frames, the layout of the insulations can be as in Figure 13.

[0034] Figure 17 shows examples of sliding leaves' layouts inside a wall chamber, recessed, in which the invention can be implemented. The first line shows 4 examples of a single-leaf frame and the second and third lines show examples of biparting frames. The examples feature one, two or three inline leaves, e.g. a glass pane, an insect screen, a shutter. Figure 18 shows corresponding layout examples for external sliding leaves. Leaves may only be sliding or tilt & slide leaves that slide externally on a surface of the wall.
